Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed September 30, 1918. Serial No. 256,231.

To all whom it may concern Be it known that I, FRED MILTON MERE- DITH, a subject of the King of Great Britain, of the city ofToronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Setting-Up Devices for Sticker or Molding Machines, of which the following is a specification.

My invention relates to improvements in setting-up devices for sticker or molding machines, and the principal object of my invention is to provide for accuracy and speed in setting up the knives in the class of machines mentioned, thereby producing a bet ter quality of work and increasing output. Another object of the invention is to make my device adjustable to fit all makes of molding machines, whether of inside or outside types. A still further object of my invention is to utilize certain fixed planes as starting points or foundations, so to speak, from which all measurements are made in setting up the knives or blades.- A still fur ther object of the invention is to make use of my device so that templets may be held thereby to permit permanent records to be made of the configuration of the cutting edge of the knives so as to facilitate the work in again setting up these knives to reproduce the same patterns. Further objects of the invention will appear in the following specification.

A device of the class described within my invention comprises a portable supporting member; a plurality of adjustable supports carried thereby, and holding or clamping means carried by said adjustable supports designed to carry the setting-up gage according to the location of use thereof and whereby the setting up of the knives carried by the vertical and longitudinal 'cutter-heads can be accurately and quickly effected.

Figure 1 is a perspective view of a settingup device within my invention. Fig. 2 is a plan view of one end of my setting-up device positioned for use against the fence of a sticker or molding machine, portion of which fence and portion of the bed of the machine being shown. This view also shows a knife undergoing adjustment. Fig. 3 is a vertical cross section on the line 33, Fig. 1, on an enlarged scale. Fig. 4 is a vertical section on the line 4.4, Fig. 3. Fig. 5 is a longitudinal section, on an en larged scale on the line 5-5, Fig. 1. Fig.

6 is a vertical cross section on the line 66, Fig. 1. Fig. 7 is a perspective view of the rear side of one of the clamps for the gageplate. Fig. 8 is a longitudinal section, on an enlarged scale, on the line 88, Fig. 7 Fig. 9 is a longitudinal section, on an enlarged scale, on the line 99, Fig. 7 Fig. 10 is an end view of the clamp for the gage plate positioned underneath the rail, showing the support therefor. Fig. 10 is a face view of one end of the gage-plate supported by one end of the clamp which is positioned underneath the rail, and Fig. 11 is a plan view of a templet upon which has been traced the cutting points of the knives for record purposes.

In the drawings, like characters of reference refer to the same parts.

It is well-known in the art that the lips of the cutter-heads of a machine, after use, are very seldom of a uniform distance from the axes of rotation thereof, and they, therefore, cannot be relied upon as starting points from which to accurately set up the knives in combination with the well-known scalegage. Now in putting my invention into practice, I support the scale-gage independently of the cutter-heads, and, therefore it is immaterial in setting up knives by means of my device, whether the lips ofthe cutter-heads be a uniform distance from the axes of rotation thereof or not, and the recult is that a comparatively unskilled oper-' ator can set up his knives very readily and with absolute accuracy, whereas according to the old practice, much time was consumed in setting up the knives, and this work could only be successfully done by highly skilled and careful workmen. It, therefore, follows that by reason of my invention, comparatively unskilled operators can do as good work in a shorter space of time, and even with less waste of material than can possibly be accomplished by skilled operators in the old way.

To set up the knives on one or more outter-heads, the supportlng' member, base, or

rail, of the device-is positioned on the bed' of the sticker or molding machine, in a manner similar to that of the pressureshoe and against the fence, after certain supporting members hereinafter referred to'have been removed therefrom. When the sup-' porting member, -base, or rail, has been positioned, the same is clamped in place'by the ordinary pressure-feet, and then the supporting members mentioned are replaced. The knives carried by the cutter heads are then adjusted to do the required work, after which the said supporting members are removed, and the supporting member is then removed from the machine.

It is to be understood that by means of my invention,the scale-gage can be supported at any angle so that the cutters or knives carried by the vertical cutter-heads may be accurately positioned, as desired.

A device within my invention comprises a suitable supporting member, base or rail A, which carries suitable supporting members hereinafter particularly referred to. The supporting member which supports the scalegage when adjusting the knives carried by the upper horizontal cutter-head, may be conveniently constructed as follows: B is a post provided with a foot C. This foot is clamped to the rail A tobe adjustable longitudinally thereof, and to be readily re moved therefrom, For this purpose, the preferred construction comprises a rail D, (supported by a block w which is carried by the rail A), having a guiding-rib E extending longitudinally thereof. The underside of the foot C is slotted to fit the rib E so that this foot may move longitudinally on the rail A. The clamping-screw F operates through a slot G formed in the foot 0 so as to allow for the adjustment of this foot and its post and the securing of the same in adjusted position, since this screw screws into the rail D. A bracket H is vertically adjustab-ly mounted on the post B in any suitable manner. The preferred construc tion comprises a key I mounted. in the bore J of the bracket and operating partly in the key-way L formed in the post B and in a correspondingly shaped key-way, formed in the bracket H. This is a construction well-known, and the bracket H is keyed from rotary movement on the post. M is a pressure-screw held in the bracket H and pinching against the key I, so as to hold the bracket H in adjusted position. Pivoted between the lugs N of the bracket M by means of the pin O, is an arm P, which, in

the position of the parts illustrated in Fig. 1, rests against the portion Q of the bracket H. Pivoted to the outer end of the arm P is a clamp R, conveniently constructed as follows: S is a plate, to one side of which is suitably secured a pair of plates T, spaced apart, between which is pivoted, by the pin U, the free end of the arm P. Formed in one of the plates T is a segmental slot 2, through which passes a clamping screw 3, carried by the arm P. The construction just described permits the clamp R to be moved into various positions and held in the required position. A is a plate overlapping one end of the plate S, and at the opposite end of this plate is a correspondingly-shaped plate 5. These plates are provided with a pair of flanges 6, as shown clearly in Figs. 1 and 9, so that the scale-gage, which is in the form of a plate 7, may be held in said clamp. Since this scalegage is to be removed from the said clamp and mounted in the other clamps with which my device is provlded, some means must be provided for permitting the ready withdrawal of the plate 7 from said clamp. To conveniently permit of this, I provide the plate 4; with an ear 8 in which is fixed one end of a rod 9 which operates through a plate 10 suitably secured at the other end to the plate S, and is secured in the plate 11, carried by the plate S, and held in spaced relationship in respect of the plate 10 so as to permit of the movement of the plate 11. For this. purpose, the said plate is slotted as shown at 12, Fig. 8, through which slot extends the screw 13 carried by the plate S. The head of this screw overlaps the sides of the slot 12. Mounted on the rod 9, and between the plates 10 and 11 is a coiled-spring a, which functionates to keep the plate a against its associated end of the plate S, when the plate 7 is not carried by the clamp R. lVhen this plate 7 is mounted in the clamp It, the plate 4: is of course held against one end of the plate 7 to retain it in place. By gripping the plates 10 and 11 in the hand, the plates 11 and rod 9 will be moved to shift the position of the flanged plate 4-.

The clamp R, just described, is that used to support the scale-gage or plate 7 when the operator is setting up the knives carried by the upper horizontal cutter-head. An identical clamp R is carried by the far end of the rail A, and this clamp is for the purpose of supporting the scale-gage or plate 7 (see Fig. 10) when setting up the knives carried by the lower horizontal cutter-head. The arm P is offset as shown in Fig. 10, and is supported by a slotted plate C cooperating with a rail D supported on the block 20 which is carried by the rail A. The clamping-screw F holds the plate C in adjusted position.

Now in order to set up the blades or knives carried by either or both of the vertical cutter-heads, I provide a supporting member positioned intermediate the clamps already described, and carried by the rail A. This supporting member is constructed very simi lar to the uppoiting member for theclamp R, and comprises a post 14 carried by a foot 15, which co-acts with the rail 16, carried by the supporting member A, after the manner well understood. The clamping screw 17 holds the foot 15 in adjusted position. The bracket 18 supports the pin 19 which pivots the arm 20 to said bracket. This bracket is mounted to turn horizontally on the post 143 by means of the head 21 chambered as shown at 22 (see Fig. 6) to receive the upper end of the post 14. The foot 23 of the bracket is in alinement with the head 21 and the post 14 passed therethrough. The said foot is provided with a pair of lugs 24, spaced apart, through which passes the clamping screw 25 so that this foot may be pinched around the post 14 to hold the said bracket in adjusted position. An open slot 26 is formed in the upper side of the foot 23 to receive the arm 20. This construction permits of the ready manipulation of this arm, and it will be understood that since the bracket 18 can be turned 011 the post 14, the clamp 27 carried by the arm 20, can be positioned to support the scale-gage or plate 7 for the setting up of the knives carried by both of the vertical cutter-heads. The said clamp 27 comprises an upper bracket composed of horizontal and vertical plates 28 and 29. By reason of the screw or equivalent element 30, the plate 29 is pivoted to the supporting member 31, longitudinally adjustably mounted on the arm 20. Through the segmental slot 32 formed in the plate 29 extends the clamping screw 33. The construction just described permits of the adjustment of the upper bracket of the clamp 27 so that the scale-gage or plate 7, carried by the lower bracket of this clamp, can be adjusted into any angular position around the screw 30, and held in this position during the setting up of the knives or blades carried by the vertical cutter-heads. The lower bracket of the clamp 27 comprises horizontal and vertical plates 34 and 35. By means of the screw or equivalent element 36, the said lower bracket is pivoted to the said upper bracket, through the medium of the plates 28 and 34. The horizontal plate 28 is provided with a segmental slot 37 through which operates the clamping screw 38 held in the plate 34 so that the lower bracket of the clamp 27 may have an adjustment inclependently of the upper bracket. Operating against the back of the plate 35, is a plate 39 provided with a slot 40, through which extends the stud 41, carried by the plate 35. Formed from the plate 39 is an ear 42 in which is held a rod or pin 43 which has sliding movement through the stud 41. A coiled-spring 44 is mounted on the pin 43 between the stud 41 and ear 42 so that the scale-gage or plate 7 may be removably clamped between the flanges a and b of the plates 39 and 35.

To prevent other than longitudinal movement of the supporting member 31 on the arm 20, suitable means is employed. The preferred means comprises a key-way 0 formed longitudinally in the arm 20 and a correspondingly shaped key-way (Z formed in the member 31, and held in these key-ways is a key 6, against which operates a clamping-screw f carried by the member 31.

I shall now describe the manner in which my device is employed. Two planes or starting points, positioned at right angles to each other, are essentially considered in making use of my invention. In setting up the cutters carried by the horizontal cutter-heads, the inner face g of the fence h (Fig. 2) must be used as a reference plane, and in setting up blades or knives on the vertical cutter-heads, the surface of the bed 2' of the machine is similarly used. As before described, to position the rail A, the clamps R and 27, and the supporting members therefor, will be removed from the rail, and after the rail A has been positioned against the inner face 9 of the rail h, and upon the top surface of the bed 2', it is clamped in position by the usual pressure feet, one only of which is indicated by the dotted line j in Fig. 2. Then the supporting member for the clamp R is placed in position and adjusted in respect of the upper horizontal cutter-head, the axis of rotation of which is indicated by the broken line in Fig. 2. The clamp R is then thrown down into the position illustrated in Figs. 1 and 2, and the scale-gage or plate 7 placed therein. This scale-gage or plate is provided with the usual scales whereby the depth and width of cut may be measured, and since it is well-known, it requires no particular description. On in scale-gage or plate, I provide at the rightlrand end thereof, two parallel lines Z and m and either of these lines must be in alinement with the imier face 9 of the rail h when setting up knives or blades carried by the upper horizontal cutter-head. The outer I line Z, I have termed the fence line, and the inner line m, I have termed the finished working line. When I am setting up blades or knives on the upper horizontal cutterhead when the vertical right hand side cutter is to be used, the fence line Z must be in alinement with the face 9. When I am setting up the knives just mentioned, and not using the vertical right-hand side cutter, the clamp R is adjusted so that when the scalegage or plate 7 is placed therein, the finished working line m, will be in alinement with the face 9 of the fence h. To secure this adjustment, I use the following preferred means: Formed in the flanged plate 5 is a pair of longitudinal slots at through which pass the screws 0. The distance separating the left-hand end of the slots n from the shank 10 of the screws 0, is equal to the distance separating the lines Z and m, and, therefore, when the plate 5 is moved to move the left-hand end of the slots a into contact with the shanks p, the screws 0 are tightened up, the finished working line m will be absolutely in alinement with the face g when the scale-gage or plate 7 is placed in the clamp R.

' We will consider'that we are going to set up the knife or blade '7" shown in Fig. 2. Naturally the same will be placed against the cutterhead (not shown), and then the cutting-edge of the knife will be positioned upon the horizontal line of the scale-gage or plate 7, required to obtain the desired depth of cut, and the said knife or blade will also be adjusted in respect of the width of the work. The adjustments once secured, the knife is clamped in place after the usual manner and the clamp R is thrown up around its pin 0 to permit the cutter-head, not shown, to be turned in order to adjust the other knives.

The clamp R receives the scale-gage or plate 7 to adjust the knives or blades carried by the lower horizontal cutter-head, and the use thereof will be understood by one skilled in this art after what has been already set forth. It will be understood that in mounting the scale-gage or plate 7 in the clamp R, the operator will use the scale backward, as shown in Fig. 10, starting his longitudinal measurements from the end vertical line indicated.

In Fig. 3, I show the scale-gage or plat-e 7 mounted in the clamp 27 so as to provide for the setting up of the cutters or blades carried by the vertical cutter-heads. The clotted line 8 represents the axis of rotation of one of the vertical cutter-heads, and the figure 2 represents in dotted lines one of the knives or cutters. In adjusting these knives or cutters, the fence-line Z is placed in alinement with the face of the bed 2', where the lower horizontal cutter-head is in use. Should the lower horizontal cutter-head be not in use, the finished working line m must be placed in alinement with the face of the said bed i. \Vithout further elaboration, it will be understood just how these cutters o1 knives are adjusted in vertical position, as before described. By loosening the clamping screw 33, the clamp 27 can be moved around the screw or pin 30 to support the scale-gage or plate 7 at the desired angle so as to secure the corresponding adjustment for the cutters or knives carried by the vertical cutter-heads. In making such angular adjustment, one of the lines Z and m must be placed in alinement with the face of the bed 2' according to which one will be used.

The bracket 18 is raised or lowered to allow for vertical adjustment of the scalegage or plate 7, by any suitable means, such as the following, when adjusting either of the lines Z and 'm in respect of the surface of the bed i, a is an adjusting screw threaded through the upper end of the head 21, and resting against the upper end of the post 14. When the required adjustment has been made, the nut 22 will be used to lock the screw u in adjusted position.

Positioned at each end of the preferred form of rail are the two blocks 'w and w whereby the bottom of the rail in the vicinity of the vertical cutter-heads will be supported above the surface i of the bed of the machine so as to allow for the free passage of cutters thereunder in case of necessity. One of the blocks to is adjustably carried by one end of the rail A by any suitable means; the preferred construction comprises a clamping screw w passing through the longitudinal slot g and screwing into a nut 2 carried by the block. A rib a, carried by the block supporting the nut 2, extends into the slot y so as to insure movement of this block longitudinally of the supporting member A. This adjusting feature just described, as well as the capability of adjustment of the supporting members for the clamps R and 27, is for the purpose of en abling my device to be used on machines of different makes.

In Fig. 11, I show a templet 60 upon which has been traced the configuration of the cutting edge of the knives set up to cut a given shape. This templet can be properly preserved so that for any future duplication of the design recorded thereon, all that is necessary will be for the operator to place the templet in the desired clamp and fit the cutting edges of the knives to the configuration of the shape carried thereby, thus greatly saving in time and insuring accuracy of adjustment.

While I have described what I consider to be the best embodiment of my invention, I desire it to be understood that the disclosure herein is merely illustrative, and I do not wish to be confined to the construc tion herein shown and described except in so far as that may be made necessary by reason of the prior art and the terms of my claims.
